Abstract

Vertically joined flooring material comprising floor boards (1), which floor boards (1) are provided with edges (2) which are provided with a groove (2&prime;), a lower side (5) and a decorative top surface (3). The floor boards (1) are intended to be joined by means of separate joining profiles (10). All edges (2) are provided with one groove (4) each, which grooves (4) are arranged parallel to its respective edge (2). The joining profiles (10) are provided with lips (11) arranged in pairs, which lips (11) each are intended to be received by the groove (4) of a floor board (1) guiding and fixing adjacent floor boards (1) horizontally. The joining profile (10) is provided with a central cheek section (13) which is comprised by a first and a second independently resilient cheek (13&prime; and 13&Prime; respectively). The cheek (13&prime; and 13&Prime; respectively) are provided with one tongue (14&prime; and 14&Prime; respectively) each whereby the tongues (14&prime; and 14&Prime; respectively) are intended to be received by one groove (2&prime;) each so that adjacent floor boards (1) are guided in a vertical direction.

Fastening system for especially floor panels hook-in connecting system, with each connection having additional locking element preventing release of connection in direction perpendicular to plane of laid panels
